The TCP Westwood congestion control algorithm was designed to improve data transfer efficiency in LTE networks. It can be applied to optimize data transmission in structural health monitoring topologies using Wireless Sensor Networks (WSN). To evaluate data transmission performance in a WSN-based structural monitoring topology, simulations of TCP Westwood were run using Network Simulator 2 (NS2). The results indicate that TCP Westwood optimizes bandwidth usage and reduces congestion, thereby enhancing data transmission performance in WSN. This allows WSNs to transmit data more quickly and efficiently, improving the quality of structural health monitoring. Additionally, by lowering bandwidth usage, TCP Westwood helps reduce WSN operational costs and maximizes network resource utilization. The study applies TCP Westwood in a building structure monitoring topology with various parameters such as the number of nodes, distance between nodes, and congestion levels. Simulation results show that TCP Westwood, particularly in topologies with more nodes and greater distances between them, enhances WSN data transmission by optimizing bandwidth usage and reducing congestion. Overall, the study demonstrates that TCP Westwood improves WSN data transmission performance in structural health monitoring, enabling faster and more efficient data transmission and reducing operational costs.
